Multiple Choice
In atomic theory, what term best describes the region of space around a nucleus where there is a high probability of finding an electron?
A
Electron shell
B
Nucleus
C
Atomic orbital
D
Valence electron
Verified step by step guidance1
Understand that in atomic theory, electrons are not found in fixed paths but rather in regions of space where they are likely to be located.
Recall that an electron shell refers to a group of atomic orbitals with the same principal quantum number, representing energy levels around the nucleus.
Recognize that the nucleus is the dense central part of the atom containing protons and neutrons, not where electrons are found.
Know that valence electrons are the electrons in the outermost shell involved in chemical bonding, but this term does not describe the region of space itself.
Identify that the term 'atomic orbital' best describes the specific region of space around the nucleus where there is a high probability of finding an electron.
